Manually cleaning your PC registry

As you know, Excel sheet is frequently acclaimed as one of the most useful software that allows users to create spreadsheets, crunch numbers as well as prepare a business report. Usually, tapping the arrow keys to move from one cell to another. However, there are times when you might experience trouble in tapping them – for instance, they won’t work when you tap them. This kind of problem can be quite frustrating since no matter what you do, especially when you tap the arrow keys, instead of a single cell, it moves the entire spreadsheet. If you are one of the users who experience this problem, worry no more for this post will guide you on what you can do to fix it. When arrow keys won’t function as intended in Excel spreadsheets, it could be due to unintended behavior of the Scroll key or it could be related to some issues with the keyboard driver. Whatever the cause is, here are some suggestions you can check out to fix it.

Option 1 – Try to disable the Scroll Lock

The first thing you can do to fix this problem with arrow keys is to disable the Scroll Lock. Although doing this is easy, newer laptops don’t actually come with it so if your keyboard does not come with a scroll key, all you have to do is tap the Fn key and disable Scroll Lock. Aside from that, you could also use the on-screen keyboard to turn off the Scroll Lock. You will see its status on the Excel sheet which will help you to double-check. Moreover, you could also tap the Shift + F14 keys to toggle off the Scroll Lock. To use the on-screen keyboard to turn off Scroll Lock, follow the steps below.

• Tap the Windows key and type “on-screen keyboard” and then tap Enter.
• Once the on-screen keyboard is opened, you should see that the Scroll Lock is on the “On” position since the ScrLk keys are in blue.
• Like pointed out earlier, you can utilize the Scroll Lock indicator located in the status bar as well as disable or enable the scroll key by using this feature on Microsoft Excel.

Option 2 – Try turning on the Sticky key

If disabling the Scroll Lock did not fix the problem, you can try turning on the Sticky Key instead. A lot of users reported that this option fixed the problem for them. So you should try to turn on the Sticky key and to do that, follow the steps below.

• First, type “control panel” in the Start Search and click on Control Panel from the search results.
• Next, select the “Turn On Sticky Keys” option and click on OK.
• After that, go back and uncheck the “Turn On Sticky Keys” option. This should fix the malfunctioning arrow keys on Excel.

Option 3 – Try running the Hardware and Devices Troubleshooter

The first thing you can do to fix the problem is by running the Hardware Troubleshooter. Although it won’t make much of a difference, there’s still a possibility that it could automatically fix the problem with these function keys. To use it, refer to these steps:

• The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
• After opening Settings, look for the Update and Security option and select it.
• From there, go to the Troubleshoot option located on the left-hand side of the list.
• Next, select Hardware and Devices from the list and open the Troubleshooter and run it. Once it is doing its job, wait for it to complete the process and then restart the system.
• After the system restarts, check if the problem’s now fixed. If not, refer to the next option given below.

Option 4 – Update the keyboard driver

You can also update the keyboard driver to fix the problem. There are cases when an outdated or corrupted driver can fix the problem. To do so, follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Then type “devmgmt.msc” in the field and hit Enter to open the Device Manager.
• From there, look for the keyboard driver and click on it.
• Next, right-click on the keyboard driver and select the Update driver option.
• After that, click the “Search automatically for updated driver software” option to proceed.

Option 5 – Reinstall the keyboard driver

If updating the keyboard driver didn’t help, then you might want to reinstall it. How? Follow the steps below.

• Tap the Win + R keys to launch Run.
• Type in MSC into the box and tap Enter or click OK to open the Device Manager.
• After that, a list of device drivers will be displayed. Look for the keyboard driver, right-click on it and then select “Uninstall device”.
• After that, unplug the device and restart your PC.
• Then plug your device back in. Assuming your device is connected to your PC, open the Device Manager again.
• Next, click on the Action button and click the Scan for hardware changes button. That should fix the problem

Note: You could also completely uninstall the driver and go directly to the manufacturer’s website and download the latest driver for your hardware and then install it.

Hello everyone and welcome to another tutorial on errortools.com, Windows itself when it is installed has a general idea about certain file types and how to open them, for example, image files would be opened with application photos, web links with the edge, etc. So when we double click on the known file type, Windows will start the default application for that type and open the file in it. But what if we do not want to open files in applications Microsoft thinks we should? What if we want to open the website in firefox or images in photoshop, or whatever. Luckily we can easily change which application Windows uses for which file type. Click on ⊞ WINDOWS to open the start menu and choose settings. On the settings screen, choose Apps. When the Apps screen opens on the left click on Default apps. On right, you will get a list of Windows default applications for certain types of files. Click on any application you would like to change and choose from the drop-down list a new one. Click on it and you are done.

In the past, CDs, DVDs, and floppy drivers used to be the primary sources of external storage for many users – that is until the USB storage devices took over. These days, a lot of devices no longer have a built-in CD or DVD writer or reader as it contributes to the thickness of the device. On the other hand, there are still various devices that still come with a built-in CD or DVD writer or reader. However, recently, users who still use CD or DVD on their devices reported a problem where the CD or DVD icon is not visible in the File Explorer as well as in “This PC” or the My Computer page. The cause of this issue is still unknown at the time of writing, but there are still some potential fixes you can try to fix it. You can try to update or roll back the device drivers or apply some tweaks in the Registry Editor. For more details, refer to the given options below.

Option 1 – Try to update or rollback device drivers

The first thing you can try to fix the missing CD or DVD icon is to either update or roll back the device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.

• Open the Devices Manager from the Win X Menu.
• Then locate the device drivers and right-click on them to open the Properties. Note that the concerned drivers will be listed under the DVD/CD-ROM drives section as well as the IDE/ATAPI Controllers section.
• From there, look for the following drivers:
  • ATA Channel 0.
  • ATA Channel 1.
  • Standard Dual Channel PCI IDE Controller.
• Now, right-click on each one of the listed drivers and update them all. You could also try to roll them back to their previous versions.

Note: You can also directly download the relevant drivers of your computer from the manufacturers’ website. So if you have an SSD, the issue might be due to an old storage driver.

Option 2 – Try to use the Registry Editor

• Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and then tap Enter to open the Registry Editor.
• Next, navigate to this registry key: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlClass{4D36E965-E325-11CE-BFC1-08002BE10318}
• After that, look for the DWORD values named “UpperFilters” and “LowerFilters”.
• Right-click on each one of these DWORD values and select Delete.
• Now restart your computer and see if it fixes the problem.

Option 3 – Try creating a new Registry entry

There is another option you can try in the Windows Registry to fix the missing icon of the CD/DVD. You can try adding a new entry. How? Refer to these steps:

• Tap the Win ­+ R keys to open the Run dialog box and type “Regedit” in the field and hit Enter to open the Registry Editor.
• After that, navigate to this registry path: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesatapi
• From there, right-click on “ATAPI” and select New > Key.
• After that, name it is “Controller0” and right-click on the sub-key and then select New > DWORD (32-bit) Value.
• Now name it as “EnumDevice1” and double click on it and then set its value data to “1”.
• Click OK and restart your computer to apply the changes made successfully.

Error Code 36 – What is it?

This is a common Device Manager Error Code that users encounter. It is commonly found on all Windows 2000 and later versions of Windows operating systems. Error Code 36 is usually prompted by the following message:

"This device is requesting a PCI interrupt but is configured for an ISA interrupt (or vice versa). Please use the computer's system setup program to reconfigure the interrupt for this device. (Code 36)"

Solution

Error Causes

Error Code 36 occurs when there is a failure in IRQ translation due to your Windows operating system getting corrupted. This is caused due to a number of triggers, such as:

• An excess of startup entries
• Errors in registries
• RAM or hardware failure
• Excessive unnecessary installed programs
• Malware or spyware

When programs are removed excessively, some programs are not removed completely and create problems in your computer’s registry.

Also, due to the presence of malware and spyware and other causes mentioned above, your computer registry builds up errors with the time that leads to slowing your PC, time lags, and even result in crashes and freezes.

Error Code 36 can cause internal and external components to malfunction or experience time lags such as DVD drive or printer and hence can severely affect your entire PC.

Further Information and Manual Repair

Error Code 36 is a severe PC error and any attempt at fixing the error must be approached with extreme caution for your PC to start functioning properly again. Here are two methods to fixing your PC.

Method 1 – Change IRQ reservation settings

Changing the IRQ reservation settings is the best way you can rely on to fix the error code. You can do this by changing the BIOS settings of your PC.

The BIOS stands for ‘Basic Input/Output System’ and is the program of your PC’s microprocessor that allows your PC to boot after you switch it on.

Caution needs to be exercised before changing the BIOS settings of your PC. This is because every PC’s BIOS version differs from another and any wrong attempt to change the settings may make matters worse.

It is therefore recommended to refer to hardware documentation that you received with your PC or motherboard and check for the model number and details of your PC’s motherboard.

Only after you have checked and confirmed all the details, should you use the specific BIOS settings required to configure your IRQ reservations?

Method 2 – Install DriverFIX

Error Code 36 isn’t an easy error to remove.

While changing the BIOS settings can work to restore your PC, it may create a whole lot of inconvenience for finding the time and effort to check the hardware documentation details and attempting to change the specific settings and especially, if your PC does not support the options to change IRQ reservations.

Given the high risks of fixing such an error, you can also install software that enables you to fix your slow PC at the click of a few buttons.

Programs such as DriverFIX can enable you to download and replace your outdated drivers with new updated ones without you having to look for them. It will detect which drivers to download based on your PC’s motherboard version from the program’s database and can get rid of error code 36.

Click here to download DriverFIX and remove error code 36 and any other type of Device Manager error from your PC.

What is Error Code 0xC004C003?

Error code 0xC004C003 has to do with activating Windows 10 after a clean install. This problem has been a frequent nuisance to users trying to update from Windows 7 or 8.1 following the invite path they got from Microsoft.

Solution

Error Causes

There are several problems that may have caused error code 0xC004C003. The most common of them are:

• The product key entered was invalid, and cannot be used to activate the new OS.
• The user followed the proper installation procedure, but the Windows update servers were too busy to handle the activation at that moment.
• The free upgrade invitation was followed but after the reinstallation, the copy of Windows 10 was still not activated.
• The user tried to perform a full clean install of Windows 10 instead of upgrading from Windows to Windows 10

Further Information and Manual Repair

A lot of solving error code 0xC004C003 has to do with the method in which the user has tried to update the system. If one decided to try and update the program before being invited to do so by the update manager, he must wait. Unfortunately, if one chooses to do it on his own and download a clean install, he was never given a product code to authenticate the process. There are two options to address error code 0xC004C003 — either restore to the previous Windows Operating System or call Microsoft (or visit their Website) and purchase a product key. The Windows update servers are very busy. There are lots of Microsoft users around the world, and the servers are doing their best to get to each and every one of the users as fast as possible, but they can only move at a certain speed. Your best bet is to sit back and wait a while. But what if you were invited, and properly downloaded Windows 10, then decided to do a clean install? It is advised that one do not try to enter Windows 7 or 8.1 serial code as this will not work. However, unlike the problem above, these users will NOT need to purchase a product key. According to Microsoft Support Staff, the installation servers are also very jammed because of the high numbers of installations going on right now. No matter what posts you may read, the key IS genuine, and it is NOT blocked, broken, or invalid. To check if Windows has been properly activated, open the Command Window. Make sure you are logged into an administrator profile; otherwise this check will not work. Type in “slmgr.vbs/ato” and click Enter and then wait. While waiting, the command will check on the status of the activation. Windows Script Host will open and show whether or not it is activated. A lot of users have reported that the activation did not work for the first few times. However they later reported after some more attempts, no issue was found in the way the operating system updated and that the activation process went smoothly. This is most likely due to the overload on the Windows Update servers, so bear with Microsoft. Users have reported that when trying to correct error code 0xC004C003, they have followed the upgrade path and then been told by Microsoft that the key was invalid and they had to purchase a new one. If the upgrade path provided by Windows 7 and Windows 8.1 is correctly followed then there is nothing to worry about Just wait a while and try it again. If there are prolonged issues, speak with a technician by visiting the Microsoft website and contacting the help center by calling the number provided. Give them all relevant information and they will be sure to help accordingly. The best solution to fix error code 0xC004C003 is to wait. In essence, the user will be waiting to reenter the same product key. According to Microsoft, and many user posts found online, it is recommended to wait a while and then try to activate again. This seemed to be an answer to most users' problems, and seem to work just fine. If the problem persists, take it to a windows repair technician to have it sorted out. If that does not work, use a powerful automated tool to fix the problem.
